DusQ3 azide

DusQ 3 azide is a highly active derivative suitable for FRET-based probes for in vivo detection and imaging. Typically used for quenching in the 620-730 nm range, DusQ 3 can be used as a quencher for rhodamine or cyanine dyes that emit red or far infrared light (eg Cyanine 5, Cyanine 5.5, APDye Fluor 647).
